John Cena appeared on ESPN2's Highly Questionable this week. During the interview, Cena discussed being fired as a limo driver and breaking into the business. Cena also said that losing to The Rock in the main event of WrestleMania 28 was his biggest shame in wrestling. Cena was also asked about his biggest shame in the business.

"I spent a year telling everybody how important that match was to me and how proud I am of all of this," Cena said. "The Rock was gracious enough to come back to WWE for one time, and one time only at WrestleMania 28 in his hometown. And I didn't get the job done."

Cena was then asked why he felt actual shame since the ending of the match was pre-determined.

"There is a giant underlying story that you may or may not know to that, and I would have really liked to have been on top that night," Cena said.

Cena didn't provide many other details, but admitted that it was "a bit of a disappointment."

"That's one of those stories that years from now, Dwayne Johnson on a seat on a table and me on a seat on a table, we'll be smoking a cigar and we'll be drinking something out of a coffee cup and we'll tell that story then... It's an interesting story and one that you'll want to hear about, so hopefully one day you will."
